LANSING, MICH. The count of Coronavirus Disease 2019 (COVID-19) cases reported by the Michigan Department of Health and Human Services (MDHHS) today includes results from commercial and clinical labs who recently began providing COVID-19 testing. These results increased the state’s positive case count to a total of 334.

“We are pleased to announce that we are now able to provide testing results from hospitals and other entities outside of our state laboratory,” said Dr. Joneigh Khaldun, chief medical executive and chief deputy for health. “We knew there were additional people in Michigan with COVID-19 that had not yet been tested. This emphasizes the need to continue to practice social distancing and other community mitigation practices to help slow the spread of this disease.”

Two of the cases initially included in today’s results have been removed; one from Genesee County and one from Isabella County. The Genesee County case was changed in the Michigan Disease Surveillance System from a positive case to not a case after data was pulled to create the tables used on the website. The Isabella County case is being removed as it tested indeterminate and has been sent to the Centers for Disease Control and Prevention for additional testing.

MDHHS is currently receiving reports from commercial labs LabCorp and Quest Diagnostics and several clinical labs including Sparrow Hospital in Lansing, the Beaumont Hospital Network, Henry Ford Health System and the MDHHS Bureau of Laboratories (BOL).

The addition of cases reported from these new labs have increased the state totals:

  Positive cases 3/18
12 AM - 11:59 PM
Cumulative positive cases
as of 3/18 11:59 PM
  MDHHS BOL 51 131
  Hospital/university* 90 203
  Commercial 1 2
  Total 142 334


The addition of these reports will allow for the reporting of the following statistics:

  • COVID-19 cases reported in the last 24 hours
  • Cumulative cases reported during the outbreak
  • Number of tests performed in last 24 hours by labs in Michigan (individuals may have more than one test result)
  • Cumulative tests performed (individuals may have more than one test result)
  • Daily counts of cases and deaths by county
  • Cumulative cases and deaths by county
  • Percent of cumulative cases by age range (in 10-year increments)
  • Percent of cumulative cases by sex

Testing data will be posted daily around 2 p.m. Results will be from the day before at midnight. Michiganders with questions about COVID-19 can get information in several ways.
